Re: P1102W has a message "Attention Required" and will not print
I just had a similar problem with my p1102w. I have been using HP compatible toner cartridges for years and this week I got "attention required" error in printer config and "Incompatible toner" in HP printer software, but could still print a test page.
Turned out I was connected on my VPN! I disconnected vpn and printer worked normally again.
